Description

A lifting mechanism for the lower mold

technical field

The utility model relates to a packaging device, in particular to a mold lifting device in a packaging machine.

Background technique

The lifting mechanism of the lower mold generally includes a lifting guide device, a power source, etc., wherein the lifting guide device includes a guide column and a linear bearing or a slider and a slide rail, etc., and the power source is a cylinder or a motor. In practical applications, the lower mold is often subject to certain pressure from the upper mold, and in some cases, the lower mold is required to have a self-locking function when it rises to the highest point.

In the existing technology, there are mainly the following ways to realize the lifting of the lower mold:

1. Directly use the cylinder that is much larger than the pressure generated by the upper mold to prevent the lower mold from being pushed down by the upper mold. However, this often makes the lifting cylinder of the lower mold have a large bore, especially for some high-efficiency packaging equipment. The air consumption of the equipment is increased, which virtually increases the user's use cost. Compared with the cylinder with a small bore, the working speed of the large bore cylinder will be reduced, thus affecting the production capacity of the packaging equipment.

2. Use the servo motor to drive the camshaft and the cam on the camshaft, and then drive the lower mold to move up and down by the cam mechanism. Although this method can not only improve the production capacity of the packaging equipment and reduce the noise during product operation, but considering the servo The cost of the motor is too high, and the pros and cons need to be weighed against its increased production capacity and reduced noise.

Utility model content

The purpose of the utility model is to provide a lifting mechanism of the lower mold with self-locking ability in view of the high cost of the lifting mechanism of the lower mold of the existing packaging equipment.

The utility model is achieved through the following technical solutions:

A lifting mechanism for a lower mold, including a bottom plate, a lower mold mounting plate, and a guide column, the lower mold is mounted on the lower mold mounting plate, the lower mold mounting plate slides up and down on the guide column, and also includes a lifting mechanism for pushing the lower mold mounting plate to move up and down Drive device, the lifting drive device includes a power source, a power source connector, a push rod, a swing rod, a connecting rod, a swing rod support seat, a connecting rod support seat, a support shaft, the output end of the power source is connected to the power source joint, and the power source The joint is connected to the swing rod through the push rod, and the other end of the swing rod is connected to the support shaft. On the support base, the swing rod support base is installed on the base plate.

Both the fork and the connecting rod are two and arranged symmetrically.

The swing rod support base is fixed on the lower end surface of the bottom plate, and the bottom plate has a groove for the horizontal movement of the swing rod.

The power source is a cylinder, the cylinder is connected to the cylinder support seat through the cylinder connection pin, the cylinder support seat is installed on the cylinder support rod, and the cylinder support rod is fixed on the lower end surface of the base plate.

A linear bearing is arranged between the lower mold mounting plate and the guide post.

Beneficial effects of the utility model: the utility model can quickly and frequently raise or lower the lower mold, so that the lifting of the lower mold becomes simple and reliable, and the manufacturing cost is low.
